(1) Random Genuine,authentic & old fossil Mosasaur tooth in original excavation matrix as found!!. It is Late Cretaceous in age (about 70 Million Years) & from the phosphate deposits in Morocco. Unique! Bundled w/ Free acrylic Stand, Fact Sheet & COA as shown. Each unusually large tooth randomly measures 1 1/4" to1 1/2" in length (some Larger) with the average about 1 1/4" in length. As is typical-Nearly all of the teeth excavated posses some typical defects such as repaired cracks or chipped tips/surfaces. These teeth are collected as a byproduct of the massive phosphate mining operations near Khourigba. The locals collected the teeth and other fossils saving them from certain destruction by rock crusher. There are as many as 10 different species of Mosasaurs in these deposits, and determining the species of individual teeth is often difficult but very possible with research. Mosasaurs are a family of enormous, marine reptiles that truly dominated the seas 90 million years ago. They ruled during the last 20-25 million years of the Cretaceous period. With the extinction of the ichthyosaurs and decline of plesiosaurs, mosasaurs diversified to become prolific, apex predators in nearly every habitat of the oceanic world. Larger mosasaurs were the great leviathans of their time, extending 10?15 m, or 33?49 ft long. Hainosaurus holds the record for longest mosasaur, at a seemingly impossible, 57 ft. The smaller genera were still an impressive, 10?20 ft long. Mosasaurs probably evolved from semi-aquatic, scaled reptiles which were more similar in appearance to modern-day monitor lizards. They had double-hinged jaws and flexible skulls (much like that of a snake), which enabled them to gulp down their prey almost whole. You will receive (1) tooth in matrix that will range in size averaging 1 1/4" in length. The Matrix on these will vary greatly and range in weight from 2-3 oz to 1 Lb.They vary in physical size from 2"x2" to about 4"x4". What you will receive is random.
